Reduced efficacy of a Src kinase inhibitor in crowded protein solution

THE EFFECT OF THEOPHYLLINE ON THE KINETICS OF cAMP-DEPENDENT PROTEIN KINASE CATALYTIC SUBUNIT, cAMP, PROTEIN KINASE INHIBITOR AND THEIR RELATIONSHIP IN LUNG TISSUE

We have investigated the effect of theophylline on the kinetics of the catalytic subunit of protein kinase and related factors in lung tissue. The results show that the point of highest concentration of the C subunit of protein kinase which is active in casein phosphorylation is at 3h of incubation time, but in the presence of 100 Ilg/ InL and 10µg/mL theophylline, this is shifted to I.S an...

Cellular SRC kinases and dsRNA dependent protein kinase (PKR) play key role in intracellular viral (CVB3) replication

SRC kinases and PKR are intracellular protein kinases, which play key roles in intracellular viral replication. In this research, the effect of SRC kinase inhibition and PKR activation and inhibition on replication of coxsakievirus (CVB3), an entrovirus of the family picornaviridae – causative agents of fatal myocarditis, was studied. Vero and Hela cells were cultured and infected with CVB3 in ...

The Src-family tyrosine kinase inhibitor PP1 interferes with the activation of ribosomal protein S6 kinases.

Considerable biochemical and pharmacological evidence suggests that the activation of ribosomal protein S6 kinases (S6Ks) by activated receptor tyrosine kinases involves multiple co-ordinated input signals. However, the identities of many of these inputs remain poorly described, and their precise involvement in S6K activation has been the subject of great investigative effort. In the present st...
